n. pl. lin·goes
The specialized vocabulary of a particular field or social group, especially when viewed as unfamiliar: computer lingo; the lingo of the local residents of the island; "the lingo that rough union guys used among themselves" (Philip Roth).
[Perhaps from Portuguese lingoa, tongue, language, or from Lingua Franca lingua, language; akin to Catalan llengua, Italian lingua, and Spanish lengua, tongue, language, all ultimately from Latin lingua; see dghū- in the Appendix of Indo-European roots.]
